Al Pastor Tacos

I've been obsessed with al pastor tacos of late, and whenever I go out of town I return home with a serious craving for Mexican food, so I thought I would finally try to make my own.  I did some research and came up with my own recipe for the marinade consisting of rehydrated Guajillo and Arbol chilis, cumin seed, Mexican oregano, pineapple chunks and whole garlic cloves, which I pureed into a loose paste.  Next I took a pork shoulder and sliced it into 1-inch steaks, which I combined with the marinade for a few hours before searing them in a cast-iron pan and setting them aside to rest.  I finished it by chopping the rested pork and putting it back in the pan with salt and more pineapple chunks to give it a nice crust, and then I served it in warm tortillas with some fresh chopped onion for some extra bite.  These turned out amazing!  The pork was smoky and savory from the chills and cumin, yet sweet from the pineapple.  I would put these up against any Mexican grandma's age-old recipe.  Bring it on, Guadalupe!
